YARN CLEANER FOR SPOOLERS.

This invention relates to a yarn cleaning and guiding mechanism for usein a spooler Such a spinning or other similar machine. device isemployed for cleaning or removing from the yarn or thread slubs, beadsor bunches of fibre and for properly guiding the yarn in its passage tothecleaner and to the yarn receiver upon which it is-wound.

The object of the invention is to provide a simpleand eflicient form ofcleaner which may be readily and accurately adjusted in order to securethe proper positioning and spacing of the comb teeth with respect to theguide rod over which the yarn passes.

The object of the invention is further to provide a simple and eflicientform of cleaner in which the comb may be readily swung away from theguide rod to permit removing the slubs, etc.,.from the yarn teeth and inwhich the comb may be swung back to oper at-ive position all withoutdisturbing its adjustment.

The object of the inventionfisf further to provide such a yarn cleanercomprising a support having an upward andrearward inclined face on whichthe comb member is pivoted, together with adjustable means for limitingthe downward swinging'movement of the comb member.

The object of the invention is further to provide a novel and eflicientmeans for effecting avertical adjustment of the guide rod in its bracketandalso for indicating its adjusted position.

The object of the invention is further to provide a yarn cleaner andtension devicein combination with a two-part bracket clamped upon thetraverse rod of the machine.

These and other objects and features of the invention will appear morefully from the accompanying description anddrawings and will beparticularl pointed out in the clalms.

The drawings i lustrate a simple and preferred form of the invention asadapted for use upon the ordinary type of spooler.

In the drawings:

Fig. 1 is a side elevation of the device with.

the traverse rod of the spooler shown in cross sect-ion.

Fig. 2 is a view similar to Fig. 1 looking at the opposite side of thedevice.

Fig. 3 is a top plan view of the device. Fig. 4: is a perspective viewof a split bushing employed in the yarn cleaner.

The device of this invention is shown as adapted to be carried by atraverse rod 1 of a spooler. spinning or similar machine in which thetraverse rod commonly has a vertical reciprocating movement'to lay theyarn throughout the len th of the yarn receiver as it is being wounthereon. In such a device it is necessary to provide means for clean-'ing or removing from the yarn any slubs, beads or bunches of fibre whichoccur and which would injure the quality of the yarn if carried on tothe receiver and also it is desirable to provide suitable guides fordirecting the passage of the yarn tot-he cleaner and suitable means forapplying the required amount of tension to the yarn, thus to insure itseven and steady movement duringthe winding or other operation.

One feature of this invention consists in providing a two-part bracket,one part of which supports the cleaning device andv the other part ofwhich supports the tension device and suitable guides with this bracketso constructed that the two parts may be rigidly clamped together uponthe interposed traverse rod. There is thus presented a very simpleandefficient-construction upon one part of which any desired form ofcleaner may be mounted and upon the other part of which any desired formof tension device or guide may be mounted. Such a bracket com-- prisesthe part 2 having at its front face a substantially semiscircular recessto fit against the traverse rod 1 and the part 3, having at its rearface a substantially semicircular recess to fit against the traverserod 1. These bracket parts have opposed vertical faces and downwardlyextended flanges. A clamping bolt 4 passes through the flange of thepart 3 and is threaded into the flange of the part 2, thus enablin thetwo parts of the bracket to be clamped rigidly together and also rigidlyto the traverse rod. The part 2 is shown as carrying the yarn cleaningdevice and the part 3 as carrying the yarn tension and guiding devices.This enables the clamping section of a usual yarn cleaner bracket to beremoved and a bracket part provided with a tension and guiding devicesuch as that illustrated to be substituted therefor and clamped to theusual yarn cleaner bracket. It also enables the tension and guidingdevices to bechanged, if desired, by substituting bracket parts carryingother forms.

The present invention also presents a novel form of a yarn cleaner. Thebracket 2 is provided with a guide rod 5 projecting laterally therefromand over which the yarn passes. This guide rod is mounted in the bracketso as to be readily and accurately adjusted vertically therein and themeans provided for this adjustment is arranged to effect a visualindication so that the vertical position of the guide rod may be readilyand accurately ascertained. For this purpose a split bushing is mountedfor rotary adjustment in a bore in the bracket part 2. The bore 6 ofthis bushing is eccentric to the bore of the bracket in which the shank7 of the bushing its and the guide rod 5 fits snugly in this bore and isheld from longitudinal movement in the bushing by a small set screw 8threaded radially into the bushing and engaging at its inner end acircumferential groove in the guide rod. A set screw 9 is threaded. intothe bracket radially of the bushing and engages at its inner end acircumferential groove 10 on the bushing. It will thus be seen that byloosening the set screw 9 the bushing may be retated in the bracket,thus varying the vertical position of the guide rod owing to the eccentricity of the bore 6 of the bushing and that when the guide rod is inthe required vertical position, it may be clamped firmly in place bytightening up the set screw 9 which both clamps the bushing against theguide rod and clamps the bushing to the bracket. Before the parts areclamped in position, the guide rod may be rotated in the bushing withoutchanging the adjustment to cause its outer angularly disposed end 11 toassume the desired position. An arcuate scale plate 12 mounted on theside face of the b .acket and the set screw 8 serves as an indicatingfinger or pointer cooperating with this scale plate so that the verticalposition of the guide rod is visually indicated thereby. Stop pins 13may also be provided to limit the extreme positions of adjustment by theengagement of the set screw 8 therewith.

A second guide rod 14 is usually provided projecting laterally from thebracket in the rear of and parallel with the guide rod 5.

The bracket is provided with an upstanding support 15 herein shown as anintegral part of the bracket and presenting at the front an upward andrearward inclined face 16 parallel with the guide rod 5.

A comb member herein shown a flat blade 17 having at its lower edge combteeth 18 secured thereto is pivoted by means of a screw 19 to thesupport 15 so as to swing on and be guided by the face 16 into and outof cooperative relation with the guide rod. The upward swinging movementwhich may be limited by a small pin 20 projecting from the plate 17engaging the support 15 is for the purpose of enabling ready access tothe comb teeth 18 so that the operator may remove the slubs, etc,collected thereon. It is very important that the comb teeth, when in inthe other direction is secured by limiting the downward swingingmovement of the comb member. This last adjustment is preferably securedby a set screw 21 threaded through the bracket, locked in position by alock nut 22 and abutting at its inner end a.

shoulder on the blade 17. It will thus be seen that the adjustment andspacing of the line of comb teeth with respect to the guide rod 5 isaccurately and readily determined in every respect. l r

The comb member is preferably held in its normal operative positionagainst the set screw 21 by a spring. The operative may readily swingthe comb member to cleaning position against the tension ofthis spring,but this spring insures automatic return of the comb member to operativeposition. A suitable helical spring for this purpose is shown at 23seated in the support 15 surrounding the pivot stud 19 and engaging atone end the head. and at the other end the comb member. It will beobserved that the axis about which the comb member 17 swings, in movingfrom its operative to its cleaning position, and vice versa, extendstransversely of or at right angles to the cooperating guide rod 5 andthat this is quite independent of the inclined feature of the supportingface 16, the only requirement in order to secure parallelism between thecomb teeth and the guide rod in this respect being that the face 16shall be parallel with the guide rod 5. q

A suitable guiding means is provided on the bracket part 3. Asillustrated, this bracket part is provided with a forward extending,forked, yarn guiding extension 24, at the throat of whichis mounted atransverse vitreous pin 25, over which the yarn passes. The bracket partis also provided with a laterally extending support herein shown in theform of a looped rod 26. A. portion of the bracket part 3 extendsbeneath this looped rod 26 and has mounted therein a vertical stud 27.On this stud is loosely mounted a disk 28 having a downwardly andinwardly bevelled periphery 29 and a hub 30 extending downwardly betweenthe members of the looped rod 26. This diskrests freely on the membersof the looped rod 26 and consequently on the yarn 31, which afterpassing over the vitreous pin passes over the rod 26 on its way to theyarn cleaner. The hub also acts as a moving lateral guide for the yarn.The weight of this disk may be varied in any suitable manner to producethe required pressure upon the yarn and consequently the requiredtension.

A guide plate 32 is secured in position by lock nuts 33 threaded on theupper end of the stud 27 and is so positioned that its lower edgeextends midway vertically of the disk 28, thus, in connection with thebevelled periphery 29, enabling the yarn to be threaded into position.
